Russ, You should be fine, we moved select users from our east coast exch 2000 server to the west coast 2007 server with no issues (albeit slow wan traffic).
Good luck -troy From: Russ Patterson [mailto:[EMAIL PROTECTED] Sent: Wednesday, March 19, 2008 7:56 AM To: MS-Exchange Admin Issues Subject: E2k7 migration question Hi all - We're getting ready to add our first E2k7 server & I had a question - in one of our two Exchange routing groups. we have a server that's in a seperate AD Site - it's a server for 150 mailboxes in a different state. We haven't decided if we're going to leave the AD site and put a 64 bit box down there, or bring the mailboxes onto servers that are here in our main AD site. Do we need to decide before we bring the 1st E2k7 server onboard? i.e. can we test a few of the out of state mailboxes on the E2k7 server to see if performance is tolerable before we make the final decision? Another 'quick' question - how 'tolerant' of Suppress Link State Routing are Ex2k3 servers - do we need to hurry the retirement of E2k3, or can they deal with Link State being gone as long as there's an E2k7 server around to make routing decisions?
